How to check for GPU on CentOS Linux

It is suggested that on Linux, GPU be found with the command lspci | grep VGA. It works fine on Ubuntu but when I try to use the same on CentOS, it says lspci comma

Answer 1

This assumes you have proprietary drivers installed, but issue the following command...

nvidia-smi

The output should look similar to this:
